A special handgun. It is extremely powerful, and it has infinite ammo. This weapon is found at the Shepherd home (first visit), on the toy chest in the children's bedroom, after finishing the game with the UFO ending.

There is one secret costume for each ending. The two main factors behind the endings are the decision to perform the mercy killing on the mother at the prison, and the decision to sympathize with the man at the church. In the case where both factors are negative, the decision to rescue the deputy at the bunker will also come into play.

Here is a quick list of the conditions for the different endings and their associated costumes:
